Features of rare earth bonded magnets:
1. Higher Magnetic Strength due to higher magnetic particle density,approximately 3 times stronger than ceramic magnet material.
2. The magnetic material is isotropic, it can be magnetized through any direction, including multi-polar arrangements.
3. Good mechanical strength. Because the material is in an epoxy binder, it can be machined on a mill or lathe. However, the material will not support a thread, so holes cannot be tapped.
4. Good corrosion resistance after Epoxy coating.
5. “Tight” tolerances off tool
6. Temperature Range -40c – 165c

Manufacturing Method
NdFeB powder is blended with a plastic material and injection molded. The resulting parts have energy products in the 5 MGOe range, but can be made with extremely intricate shapes.
Injection Bonded NdFeB Magnets for professional use
These magnets are produced by fairly conventional injection molding techniques, using a high loaded compound of either ferrite or NdFeB powder in a nylon or plastic matrix. The applications grew dramatically in the 1980s around the consumer product markets.
